by the frame tag. However, when this switch receives an untagged frame
from a VLAN-unaware device, it first decides where to forward the frame,
and then inserts a VLAN tag reflecting the ingress port's default VID.
Enabling or Disabling GVRP (Global Setting)
GARP VLAN Registration Protocol (GVRP) defines a way for switches to
exchange VLAN information in order to register VLAN members on
ports across the network. VLANs are dynamically configured based on
join messages issued by host devices and propagated throughout the
network. GVRP must be enabled to permit automatic VLAN registration,
and to support VLANs which extend beyond the local switch. (Default:
Disabled)
Web – Click VLAN, 802.1Q VLAN, GVRP Status. Enable or disable
GVRP, and click Apply.
